Abstract

Deciphering the dominant controls on interconnections between groundwater, surface water, and climate is critical to understanding water cycles in arid environments, yet persistent uncertainties in the fundamental hydrology of these systems remain. The growing demand for critical minerals such as lithium and associated water demands in these arid environments has amplified the urgency to address these uncertainties. We present an integrated hydrological analysis of the Dry Andes region utilizing a uniquely comprehensive set of tracer data (3H, 18O/2H) for this type of environment, paired directly with physical hydrological observations. We fi...  more
